Developing new Schiff base molecules for selective colorimetric sensing of Fe3+ and Cu2+ metal ions: Substituent dependent selectivity and colour change
Abstract New Schiff base chemosensors (1–5) based on aryl ether amine were synthesized and explored the colorimetric sensing of metal ions. A highly selective colorimetric sensing of Fe3+ ions was… Expand
Selective fluorescence sensing of Mg2+ ions by Schiff base chemosensor: effect of diamine structural rigidity and solvent
Highly selective strong turn-on fluorescence for Mg2+ (Φ = 0.03 to 0.57) was realized with a simple Salen based Schiff base chemosensor (1a) using dimethylformamide (DMF) or dimethyl sulfoxide (DMSO)… Expand
